To all whom it may concern: I

Be it known that I, PHILIP Hniannsrrxon, 0 the city of Dayton, county of Montgomery and State of Ohio, have invented a new and use ful Barbers Chair with Reversible Seat and Back; and I do hereby declare that the following is' a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making apart of this specification, in which- Figure I is a perspective front view of the chair. Fig. II represents a rear and side view. Fig. III represents parts of the machinery of the chair.

The chair is of the figure and shape as rep-- resented in Figs. I and II; and on the drawing the legs of the chair are represented by the letters a b c (1. These legs are connected, near the. bottom, by stretchers, respectively lettered e f g h; and are also connected at the top by stretchers i, j, k, and l. on the sides of the chair are the arms, marked m and a. If this chair is made of metal the legs a and d, stretchers e and l, and arm at are cast in one piece; and legs I) and c and stretchers g and j and arm nare also cast in one piece, and are connected together by the stretchers f and t in front, and stretchers h and L in the rear, and the whole fastened together by screws. The stretchers i, j, k, and 1 form the outside frame of the reversible seat. The back of the chair is an oval frame, marked 0, supported by a stretcher, p, and two upright pieces, marked (1 and 1', extending from near the ends of the stretcher p to sides of oval frame. The oval frame 0, stretcher p, and side supports q and r are cast in one piece. Stretcher p ends in and runs in bearings on the sides of the chair-frame. The seat of the chair, marked 8, rests in front upon a pivot in stretcher 2, and upon a bearing in a journal in the rear in stretcher k, the bearing ending in a fixed grooved pulley, t, on the outside of the stretcher k. The seat. 8 turns upon said pivot and said bearing inside of the frame of seat. On each side and near the back of the chair is a lever marked a u, running in bearcrank-shaft is attached to stretcher k by a spring marked s19. These levers u u, having one common motion, move a slide marked w w, one on each side of the chair. These slides to 'w are fitted on the inside of the levers by two projections, the levers Working in a loose joint. The forward end of these slides to w runs through a groove in the sides of seat-frame, (stretchers j and 1,) and ends in a projection, one on each side of stretcher j and of stretcher l. The projections on the inside of stretchers 7' and 1 run in and fit into a clutch marked a: so, one on each side of the seat 8, thus fastening the seat when the lever is at rest. In the rear end of the chair, and near the floor, there are two treadles, marked 3 y, hung upon a crosspiece marked Z. This cross-piece Z extends from stretcher e to stretcher g, near the front part of the chair. To the right treadle y, and near the foot-end thereof, there is fastened, by a link, a cord, marked A, which cord runs up ward over the fixed grooved pulley t, and is fastened to said fixed grooved pulley by a pin, wedge, or screw; and said cord A runs thence downward, and is fastened to the left treadle y in the same manner as toright treadle. The back of the chair, marked B, is made to fit into the oval frame 0, and turns on the top on a projectionlet into a round hole in the top of back 13, as hereinafter described. 011 the lower end of the back B there is a grooved pulley, D, fastened to said back, which grooved pulley ends in a pivot in the center of stretcher 12. On the rear'side of the stretcher p, and on each side of the fixed grooved pulley D, there are two. movable pulleys, E E, running perpendicularly in bearings attached to a projection fastened to the center of stretcher 1). Near the middle of the right treadle y there'is fastened a cord, running thence upward overthe right grooved pulleyE, and around and fastened to fixed pulley D thence over the left pulley E downward, and is fastened to the left treadle y near the middle thereof. On each side of the crank-shaft o there are two cranks,
